Anworth Mortgage Asset Corporation Announces Dividend Tax Information for 2006.

SANTA MONICA, Calif. -- Anworth Mortgage Asset Corporation (NYSE:ANH), a real estate investment trust (REIT), announced today tax information regarding its dividend distributions for the year ended December 31, 2006.

Stockholders should check the tax statements they receive from brokerage firms to ensure that the Anworth dividend information reported in those statements conforms to the information reported herein. Furthermore, stockholders should consult their tax advisors to determine the taxes that should be paid on Anworth's dividends.

As a REIT, Anworth's dividends are generally not eligible for rate reductions enacted for certain types of dividend income under the Jobs and Growth Tax Relief Reconciliation Act of 2003. Thus, the portion of Anworth's dividends that are characterized as ordinary income generally will be taxed at full ordinary income rates. For stockholders that are corporations, Anworth's dividends are not eligible for the corporate dividends-received deduction.

As each stockholder's tax situation may be different and each dividend distribution may have its own separate tax status, the tables below provide the detailed tax information for each of Anworth's dividends for 2006:

Because Anworth is a REIT, dividends declared in the last month of a calendar year with a record date in that calendar year, but which are payable in January of the following year, are considered paid for Form 1099 reporting purposes on the record date, not on the payable date, to the extent the REIT has any remaining undistributed earnings and profits (as computed for income tax purposes) as of December 31 of that calendar year. The amounts shown above in the column labeled Carry Over to 2007 represent the per share amount of the distributions payable in January 2007 which exceeded Anworth's undistributed earnings and profits for income tax purposes as of December 31, 2006. These amounts will be treated for income tax purposes as 2007 distributions to the Anworth stockholders to whom the distributions were payable in January 2007.

Dividends may be reinvested through Anworth's Dividend Reinvestment Plan. Plan information may be obtained from the Plan Administrator, American Stock Transfer and Trust Company, at 877-248-6410, on Anworth's web site at www.anworth.com, or by contacting Anworth.
